Regular readers will know I am quite a fan of these heritage trips, not just because the train itself is a delightful old thing, but mainly for the joy of watching the looks of total shock and surprise from passengers waiting for a normal train, as the little old red train pulls into stations – and drives off without collecting anyone.

Leaving Northfields on the Piccadilly line the train travels into London, to High Street Kensington via Earl’s Court experiencing an unusual cross over from the Piccadilly line to the District line, from here you will travel back down the District line again changing onto the Piccadilly line at Acton Town.

The journey taking in all three terminals at Heathrow in a single trip is most unusual, from Hatton Cross it will take a left turn and run to Heathrow Terminal 4 and carry on to Terminals 1, 2 and 3 where will it will perform the Fish Hook Move and – subject to final approval – reverse down to Terminal 5 before the return journey to Northfields.

There are three trips on the day – starting at 9:10am, 11:26am and 2:10pm – trips last about 2 hours.

Cost: Adults £25; Children £15

You can purchase tickets for this special trip, by telephone on 020 7565 7298 or you can Book Online (caveat emptor – the website seems wobbly at times – I’d recommend phoning them).

I think £25 is far too steep. I’m struggling to see the art deco in the vintage tube train carriage above. Apart from the fact that it’s obviously clean, and has a wooden floor and window frames, it’s hard to distinguish it from the decrepit trains we travel on every day.
